Some modules not fit photos

I noticed that some of my modules such as "Groups" and "Humor and Jokes" do not display the entire picture. Only small images are located in the block, larger fall outside the block and you can not see the whole.

You can check this fo example here: http://www.areavis.com/m/humor/view/Dziwne-i-straszne-zdj%C4%99cia-z-Google-Street-View

I would like to adjust the image size to the block that picture was seen in all. Maybe there is a javascript conflict? How can I fix this?

this might fix it: go to your admin section / modules / photos, & change the Width Of Main Photo Unit

 Thanks, I do this but its not helped, I changed to 400, 900 but nothing changes with photos. Is there any other way to fix it?

Modules> Photos> Settings

Width Of Main Photo Unit (In Pixels):

Change from 750 to 550.

It won't resize previous uploads though. Only afterwards.
